Advantage is better control over the clutch for faster or smoother shifting. Disadvantage is if you have poor clutch control you're more likely to stall or do damage to drive train components as full power without clutch slip can be transmitted directly.

(in my opinion) better to let your clutch take the abuse and be the failure point than other parts of your drivetrain |

worth noting that most new BMW transmissions don't have a removable CDV. Its now built directly into the transmission, so no easy way to replace like you could on the E9x chassis.
